Answer:

120 = 15x + 45   5 hours of lessons

Step-by-step explanation:

120 is total money so that goes on one side.

45 is a one-time cost so it is on its own.

15 per hour is another cost but this one depends on a variable so it has an x.

X represents the number of hours.

You put this together to from the equation: 120 = 15x + 45.

Subtract 45 from both sides: 75 = 15x

Divide 15 from both sides: 5 = x.

X = hours so 5 hours

Answer:

About 400 times

Step-by-step explanation:

Given

[tex]n = 1060[/tex]

See attachment for spinner

Required

Determine the number of times an outcome of 1, 3 or 8 is expected

First, calculate the theoretical probability of 1, 3, or 8

This is calculated as:

[tex]Pr = P(1) + P(3) + P(8)[/tex]

The spinner is divided into 8 equal segments and each outcome appears once.

So, we have:

[tex]Pr = \frac{1}{8}+\frac{1}{8}+\frac{1}{8}[/tex]

Take LCM and add

[tex]Pr = \frac{1+1+1}{8}[/tex]

[tex]Pr = \frac{3}{8}[/tex]

So, the expected number of times (E) is:

[tex]E = Pr * n[/tex]

[tex]E = \frac{3}{8} * 1060[/tex]

[tex]E = \frac{3* 1060}{8}[/tex]

[tex]E = \frac{3180}{8}[/tex]

[tex]E = 397.5[/tex]

Approximate

[tex]E = 398[/tex]

This means about 400 times

Answer:

The length of each blue trim is 17.2 inches

Step-by-step explanation:

Given

See attachment for banner

Required

The length of each blue trim

Since all 4 triangles are equal, then the dimension of 1 triangle is:

[tex]Side\ 1 = 10[/tex]

[tex]Side\ 2 = 14[/tex]

The hypotenuse (x) of the triangle blue trim is represented by the blue trim

So:

[tex]x^2 = Side\ 1^2 + Side\ 2^2[/tex]

This gives

[tex]x^2 = 10^2 + 14^2[/tex]

[tex]x^2 = 100 + 196[/tex]

[tex]x^2 = 296[/tex]

Take square root

[tex]x = \sqrt{296[/tex]

[tex]x = 17.2in[/tex]

Answer:

x = 37

Step-by-step explanation:

Well if you didn't know vertical angles are congruent ( or equal to each other )

Which means that 74 = 2x

If we want to find the value of x, then we need to get rid of the "2" on 2x

To do so we can divide each side by 2

74 / 2 = 37

2x / 2 = x

we would be left with x = 37

Answer:

The correct option is d. Project B.

Step-by-step explanation:

Note: See the attached excel file for the calculation of the Cumulative Cash Flows of Projects A and B.

Payback period refers to the number of time or period that is needed to recoup the amount of money spent a project. The

payback period rule states that when considering two or more projects, a project with the shortest payback period should be selected.

Payback period can be calculated as follows:

Payback period = Time before full recovery + (Unrecovered cost at start of the time of full recovery / Cash flow during the time of full recovery) ………………. (1)

Using the information in the excel file (in red color), equation (1) can be calculated for Project A and Project B as follows:

Project A payback period = 2 + ($1,000 / $3,000) = 2.33

Project B payback period = 2 + ($3,000 / $10,000) = 2.30

Since the payback period of Project B payback period which is 2.30 is lower than the Project A payback period of 2.33, Project B should be selected.

Therefore, the correct option is d. Project B.

So, if she brought 2 tickets an they cost £4.00 you would add £4.00 + £4.00 = £8.00 and then you would take that away from the £10.00 - £8.00 = £2.00 so Emma would get £2.00 change :) hopefully that helps you.

Answer:

C

Step-by-step explanation:

The formula to find the slope of a line is:

(y2 - y1) / (x2 - x1)

We can substitute the points (-4, 7) and (5, -8) to find the slope:

(-8 - 7) / (5 - (-4))

(-15) / (5 + 4)

(-15) / 9

This can be simplified to

- 5 / 3

which is option C

Answer:

-5/3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-8-7)/(5-(-4))

m=-15/(5+4)

m=-15/9

m=-5/3

Step-by-step explanation:  5 19 7 36

Alondra studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science and history.

Write an equation and find the solution

Total hours = english hours + ( math + science + history ) hours

Total hours = english hours +  other subjects hours

    7 hours  =  1 hours  +  3( x ) hours     solve for x

     (7 - 1) hours  =  (1 - 1) hours + 3x hours

          6 hours / 3  =  3x / 3    hours

                2 hours  = x hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let's call the number of minutes used in a month "m". For the first plan, the cost is a fixed $35 for up to 450 minutes, and then an additional $0.16 per minute for any minutes used beyond 450

C₁(m) = 35 + 0.16(m - 450)

For the second plan, the cost is a fixed $55 per month for unlimited minutes

C₂(m) = 55

when C₁ = C₂ , we get

35 + 0.16(m - 450) = 55

Subtracting 35 on both sides , we get

0.16m - 72 = 20

Adding 72 on both sides , we get

0.16m = 92

Divide by 0.16 on both sides , we get

m = 575 minutes

Hence , the number of minutes is m = 575 minutes

Mrs. Watanabe is choosing a cell phone plan. One plan costs $35 a month and includes 450 minutes. The charge for each minute over 450 is $0.16. The company also offers an unlimited calling plan with a $55 monthly charge.At how many minutes would the cost of the two plans be the same?

Answer:

13/15

86.67%

Step-by-step explanation:

non red marbles = 13

total marbles = 15

13/15 = 0.866667

86.67%

log(3x) = log(2x-4)

taking antilog of both sides:

3x = 2x - 4

3x - 2x = -4                    [subtracting 2x from both sides]

x = -4

T= 3.56

Reject

Step-by-step explanation:

The estimated equation of an employee's commitment to the business (Y) based on the amount of hours they spend meditating (X) is:

[tex]\hat Y = 45.63 + 3.60 *X[/tex]

Also;

[tex]\hat \beta_1[/tex] the coefficient of X from the equation Y on X = 3.60

Standard error  S.E [tex]\hat \beta_1[/tex] = 1.01

The null & alternative hypothesis:

[tex]H_o : \beta_1 = 0 \\ \\ H_1 : \beta > 0[/tex]

Test statistics:

[tex]T = \dfrac{\hat \beta _1}{S.E (\hat \beta _1)}[/tex]

[tex]T = \dfrac{3.60}{1.01}[/tex]

T = 3.56

Value of T-statistics = 3.56

P-value = P(t > T)

here;

t = standard t variable  with a degree of freedom = 100 - 1 = 99

∴

P value = P(t > 3.56)

P value = 1 - P(t < 3.56)

P value = 1 - 0.9997

P value = 0.0003

Since p-value is less than ∝ at 0.05

We reject the [tex]H_o[/tex]  (null hypothesis)
